Suge Knight arrested after fatally running down a friend

Notorious former music exec Suge Knight has been arrested after fatally running down a friend on the set of the movie, 'Straight Outta Compton' after getting into a fight with security. He reportedly then backed up over the men he hit as he fled the scene. Full report from TMZ below..

Multiple witnesses tell us a movie shoot -- involving Ice Cube and Dr. Dre -- was going down when Suge pulled up in his car. We're told security told Suge to leave and that's when trouble began.

A fight broke out between Suge and 2 men. Suge got back into his car, took the wheel and threw the vehicle in reverse ... and ran over a man who suffered fatal injuries.

It's unclear at this point if the victim was connected to the movie. A source close to Cube tells us production had wrapped when the fight went down ... and he and Dre were not on set.

Sources connected with Suge tell TMZ ... the 2 men who fought Suge were the instigators. Our sources say Suge was scared because he's in frail health -- in addition to being shot 6 times last summer, he recently almost died from a blood clot.

The victim is Terry Carter, who we're told is a friend of Suge's who arrived with him at the scene. Our sources say Carter was in the process of walking to the passenger door of Suge's vehicle, but happened to be in the rear when Suge gunned it.

Two other men were also hit ... including Cle "Bone" Sloane -- who's appeared in "Training Day" and "End of Watch" -- and suffered non-life threatening injuries. Both men are in the hospital.

Suge has been placed under arrest and is being held on $2 million bail.
